T-Mobile doubles your data when you add a tablet to your Simple Choice plan

Example time, boys and girls. Let's say you have a Simple Choice smartphone plan that gives you 5GB of data a month. You can add your connected tablet for $10 and receive another 5GB of data, held aside just for your tablet. And of course, there is that additional 200MB of data for your slate that T-Mobile gives away to customers, for the life of their T-Mobile tablet.
"The old school carriers make you pay for the privilege of connecting your tablet to their network−just to tap into the same limited pool of data you already bought for your smartphone. With the Un-carrier, you can now get double the data on a network designed for data for one simple price. It couldn’t be simpler or more straightforward."-John Legere, CEO, T-Mobile
Will Verizon, AT&T or Sprint respond? Stay tuned.
